Hi @karenza . You might be able to buy an Australian SIM card in your home country (or buy one when you arrive), cheapest plan you can find. Once in Australia, you can port that number to TPG. They mail their SIM card to an address.
Hi @karenza
The system requires an active Australian mobile number to order a TPG SIM.
If you have a family member or friend in Australia, you may ask if you can use their number for the registration. You can change it afterwards.
david64 advise will do as well.

You'll get a new number. The number that you'll use is for notification only and for the activation of the new SIM.
There's no difference if you use a non AU card as long as it is Visa or Mastercard.
Can you close the browser, then open it up again? Try a different browser if possible.
Let us know how it goes.
